PROPORTIONATE SCALE.

SPECIFICATION forming' part of Letters Patent No. 657,476, datedSeptember 4, 1900.

Application filed May 29 1900. Serial No.18,388. (No model.)

T @ZZ whom, t may concern:

Be it known that I, GEORGE R. BROWN, a citizen of the United States, anda resident of Pledger, in the county of Matagorda and State of Texas,have invented a new and Improved Proportionate Scale, of which thefollowing is a full, clear, and exact description. Y

This invention relates to improvements in scales for determining therelative proportion or percentage of a product and the tare or waste,and a main object is to provide ascale of simple construction for theuse of ginners in buying cotton-seed and to enable a purchaser todetermine the percentage of lint contained in the seed-cotton offeredfor sale.

I will describe a proportionate scale embodying my invention and thenpoint out the novel features in the appendedclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a proportionate scale embodyingmyinvention. Fig. 2 is a sectional side elevation thereof, and Fig. 3 isa transverse section on the line a' of Fig. 2. The scale comprises abalance-beam l,which is made tubular or in the form of a box, the top ofwhich, at one end, however, is removed, as at 2. This beam 1 is mountedto rock on a shaft 3, which has bearings in supports 4, extended upwardfrom a base 5. Rigidly attached to the beam 1 at one side of itsfulcrum-point is a tray 6, and movable lengthwise of the beam at theopposite side of its fulcrum-point is a tray 7 for receiving tare orlint. p This tray 7 has downwardly-extended arms 8, in which thespindles of a grooved roller 9 have bearings. Extended from the arms 8and lengthwise of the beam, at the upper portion thereof, is a rack l0,which passes over a roller 11, from the spindles of which a rack 12extends along the bottom of the beam and underneath the roller 9. isflanged like the roller 9. Therefore these rollers, with the racks,serve not only as a means for moving the tray 7, but also as a guidetherefor. The roller l1 is made solid, while the roller 9 is made inspoke form. Therefore the roller l1 further serves as a The roller 11counterpoise for the tray 7 and its supporting-roller 9.

A pinion 18 is mounted on the shaft 3 and meshes with the racks 10 and12, and connected to the shaft 3 at the outcrside of the beam is ahand-Wheel 14, on the outer face of which are figures 15, designed toindicate the proportion or percentage of the two articles in the trays 6and 7. bers is a pointer 16, which is supported on arms 17, connected toone side of the sealebeam. It is obvious that by rotating the wheel 14the counterpoise l1 and the tray 7 may be caused to move toward or fromeach other, as desired, to balance.

As the rate of lint to the seed-cotton is from twenty-five to forty percent., the construction of the scale is such as to indicate thepercentage between twenty-live and fifty per cent. yfor the purpose ofmaking the scale as equilibrium is established. He can then read fromthe index-plate, say, thirty-three per cent., showing that theseed-cotton contains thirty three pounds of lint per hundred pounds ofseed-cotton, and thus the actual lint product of the load may bedefinitely ascertained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A proportionate scale, comprising a balance-beam,a tray fixedly supported on said beam, a tray movable along said beam,aroller supporting the tray, a rack extended from said movable tra-y, acounterpoise-roller movable in the beam, a rack extended from saidcounterpoise-roller, a pinion engaging with said rack, and a hand-Wheelon the shaft of said pinion, said hand-Wheel being provided with ascale, substantially as specified.

2. A proportionate scale, comprising a hol- Ooacting with these numinggage-marks on its outer surface, and a pointer carried by the beam forcoaching with said scale, Substantially as specified.

In testimony whereof I have signed my 15 name to this specification inthe presence of two subscribing` witnesses.

GEORGE R. BRO\VN.
